WALKER, or SAME PLACE.

IMPROVEMENT IN CRAYON-HOLDERS.

Specification forming part of Letters Patent No. 137,844, dated April16,1673; application filed March 20, 1873.

To all whom itmay concern:

Be it known that I, ANDREW F. HOWARD, of Waltham, of the county ofMiddlesex and State of Massachusetts, have invented a new and usefulImprovement in GrayonHolders, and do hereby declare the same to be fullydescribed in the following specification, and represented in theaccompanying drawing, of which- Figure l is a side View; Fig. 2, alongitudinal section, and Fig. 3, a front end view of one of my saidport-crayons with a crayon in it.

If constructed as shown, it is intended for holding a conical ortapering crayon or chalk, such as now used in schools for marking onblack-boards, or for other purposes in the arts.

The article in question consists, first, of a thin metal tube, A, madetapering for about a third or a half its length from one end, and havingfrom such end a series of slits, a a, made in it longitudinally, asshown, so as to form of the tube a series of springs, 11 b b,- second,of a tapering collar or tube B to slip on such tapering part 5 third, ofathimble or cap,

' O, to fit to and estop the other end or mouth,

and so made and applied thereto as to be capable of being separatedtherefrom, such cap being held in place by friction or a screw.

The crayon, shown at D, is inserted into the tube at its mouth or longerend when open, the cap being subsequently being put in place so as tocover such end. The smaller end of the crayon being drawn out beyond thesplit end of the tube to the desirable extent, the

collar B is to be passed over such end and upon the springs of the tubeA, so as to compress such springs upon the crayon and cause them to holdit in place in order that it may be used or drawn with while theport-crayon or crayon-holder is held in the hand of a person. Afterward,and after having loosened the clamp-tube B, the crayon may be pushedback wholly within the tube A, and thereby the crayon will be protectedfrom injury while not in use, or while being transported from place toplace.

I do not confine the tube A to the precise form shown, as such may bevaried somewhat without changing the character of the invention.

With the common double port=erayon, hav ing twojaws at each end, thecrayon is exposed or not Wholly incased on its sides and upper end, butin my single or improved port-crayon the crayon is fully-protected onits sides and upper end. a

' I therefore claim the improved article of manufacture or port-crayon,composed of the tapering and slitted tube A, the thimble or cap O, andthe tapering or tubular collar 13, constructed and arranged essentiallyas shown and described, the crayon receiving-mouth in such port=crayonbeing at the upper end or part of the article, as set forth.

ANDREW F. HOWARD.
